Serverless FaaS Architecture & Cloud+ Certification

1. What is the primary runtime environment concern when selecting a FaaS platform?

The color of the dashboard interface

Supported programming languages and versions

The number of administrators available

The physical location of data centers only

2. What is a common security consideration when deploying FaaS functions?

Functions should store API keys and secrets directly in the code

Functions must use environment variables or secret management services for sensitive data

Security is not relevant in serverless environments

All functions should have public access endpoints

3. True or False: FaaS functions can be invoked synchronously and asynchronously.

True

False

4. Which monitoring metric is most critical for FaaS cost optimization?

Server CPU temperature

Function execution duration and invocation frequency

Network cable bandwidth

Physical disk space usage

5. In FaaS, what is typically included in the function's execution context or handler?

The operating system kernel

Server hardware specifications

The event data, request parameters, and callback functions

The physical network configuration

6. How do FaaS platforms typically handle automatic scaling?

You must manually adjust capacity settings

The platform automatically creates new function instances based on incoming requests

Scaling only occurs during scheduled maintenance windows

Scaling is not supported in FaaS environments

7. What does the term 'event-driven' mean in FaaS architecture?

Functions run continuously regardless of activity

Functions execute only in response to specific events or triggers

Events are logged but do not trigger function execution

Functions must be manually invoked by an administrator

8. Which of the following is a common use case for FaaS?

Running a traditional monolithic web application

Processing image uploads triggered by S3 events

Hosting a high-traffic relational database

Managing long-running batch data transformations

9. True or False: Serverless FaaS requires you to manage the underlying operating system.

True

False

10. In FaaS, what role does an API Gateway typically play?

It stores function code and configurations

It routes HTTP requests to appropriate functions and manages authentication

It monitors network traffic only

It compiles functions into executable binaries

11. Which of the following best describes Functions as a Service (FaaS)?

A service where you deploy entire applications as containers

A model where developers write and deploy functions triggered by events without managing servers

A traditional virtual machine hosting service

A database management platform

12. How does FaaS typically handle state management?

Each function maintains permanent state in memory

Functions are stateless; state is stored externally in databases or caches

All state is stored locally on the server

Functions automatically sync state across all instances

13. Which cloud provider offers Cloud Functions as their FaaS solution?

Microsoft Azure

Google Cloud

IBM Cloud

DigitalOcean

Submit

15. What does 'cold start' mean in the context of FaaS?

The initial cost charged when deploying a function

The delay when a function is invoked after being idle

A security measure that prevents unauthorized access

The process of testing a function before deployment

16. Which of the following is NOT a typical characteristic of serverless FaaS?

Automatic scaling based on demand

Event-driven execution model

Manual provisioning of server capacity

No operational management of infrastructure

17. In FaaS, what is typically the maximum execution duration for a single function invocation?

Unlimited; functions can run as long as needed

Usually 15 minutes or less, varying by provider

Exactly 5 minutes for all providers

Up to 1 hour maximum

18. What is a key advantage of FaaS regarding cost management?

You pay for reserved capacity upfront

You pay only for the compute time your functions actually use

There are no additional costs beyond the cloud platform subscription

You must purchase licenses for each function deployed

19. Which AWS service is the primary FaaS offering?

AWS EC2

AWS Lambda

AWS RDS

AWS S3

20. In a serverless FaaS environment, what typically triggers function execution?

Manual scheduling by administrators

Continuous polling of a database

Events such as API calls, file uploads, or message queue entries

Background batch jobs running on a fixed schedule
